SKEINING APPARATUS.

Application filed June 15,

My invention relates to skeining apparatus, and particularly to apparatus for winding a plurality of skeins upon a single reel. The object of my invention is to provide a layout in which the tension on the threads is reduced and also rendered substantially constant. It is also uniform in each skein wound on the reel.

In the accompanying drawings Fig. 1 is a frontelevation of an apparatus in which my invention is embodied in one form; and

Fig. 2 is a side elevation thereof.

My invention relates particularly to the skeining of fragile threads such as those of artificial silk, in which reduction of stress upon the threads is of importance in view of the fact that the skeining operation is commonly performed at a stage, in the course of manufacture, when the thread is. still quite fragile. My invention insures a substantially constant. stress on the thread during the reeling operation, and this is highly desirable under all conditions. Again my invention insures uniformity in the skeins wound on the same reelanother factor of importance.

I have indicated in the accompanying drawings, mechanism adapted for a skeining operation performed at the usual stage in the manufacture of the thread in this art that is to say, the skeining of the silk from the cake or bobbin in which the silk is gathered directly after leaving the setting bath, and the silk being wound in skein form for subsequent treatment, such desulfiding, bleaching, dyeing, etc. It is to be understood, however, that my improve ments are applicable to a skeining operation performed at any stage of the process.

In the accompanying more or less diagrammatic drawings, 1 have indicated a frame adapted to support like reeling mechanisms on opposite sides thereof, those on only one side being shown. The frame comprises standards suitably spaced longi tudinally of the frame, and mounted for vertical adjustment on pedestals lti, so that the standards and the parts supported thereby may be raised or lowered, as desired. At their lower ends the flanges 17 of the standards are pierced by series of vertically spaced apertures 18. Brackets 19, vertically adjustable on these flanges, support horizontally adjustable platform boards 20 and 1927'. Serial no. wanes.

21 on which the fiber cakes 22 and 23 rest during the skeining operation.

Adjacent the upper ends of the standards 15 are longitudinally extending tie bars 2% which serve as supports for vertical pins Vertically adjustable on these pins are sup porting arms 26 which, at their outer ends, carry longitudinal beams 27. Spaced aloha the beams 27 are stationary guide arms 28 and 29. i Resting on the tops of the standards 15, 1s a longitudinal channel 30 which carries frames (not shown) for supporting the reels, pf wlnch only one, viz 31, is indicated. lhe reel drive may be of any appropriate character, such for example as that shown in the copending application of Thompson,v

Ser. No. 201,526, filed June 25, 192?. i A traverse arm 32 is adnistably mounted on a rock shaft 33 driven by the reel, and carries at its outer end a traverse bar 34L. A plurality of thread guides 35 is carried by each traverse bar, two being shown in the present instance for winding two skeins 36 and 37 on the reel 31.

It will be noted that thetraverse guides 35 are located in a vertical plane substan, tially parallel with the axis of the reel and tangent to its periphery.

It will be noted that the fixed guides'28 and 29 have thread guideways 38 and 39 respectively located substantially in line with the vertical axes of the cakes 22 and 23, and are also symmetrically located on opposite sidesof the vertical plane of the traverse guides 35. The spacing of the guideways 38 and 39, and the location of the fiber cakes on opposite sides of the vertical plane of the traverse guides 35, is governed by the ballooning of the threads 40 and 11 as they unwind from the fiber cakes (or bobbins), 9

and they are so located as to prevent interference between the threads as they float around the cakes 22 and 23 during the skein- 1ng operation.

It will also be noted that each traverse guide 35, when in its median position, is in the same vertical plane, normal to the axis of the reel shaft, as the cooperating stationary guide 38 or 39 and the axis of the fiber cake 22 or 23, from which the thread is fed.

This layout insures the least possible angular deflection of the thread as it passes from the fiber cake through the stationary guide, and the traverse guide to the reel 31.

Consequently the thread is placed under the least possible stress. Moreover, since the arrangement is symmetrical with respect to the course of the thread from guides 38 and 3!) to the reel 31, and from the guides 38 and 39 to the respective fiber cakes 22 and 23, a uniformity of stress on the threads in the respective skeins 36 and 37 is maintained. Again, the symmetrical arrangement of the traverse guides 35 with respect to the fixed guides 38 and 39, insures substantially constant tension upon the thread throughout the traverse motion.

The reduction and constancy of the tension on the thread, and the uniformity of the several skeins. are of importance in the manufacture of artificial silk, not only from the standpoint of reduced breakage (and consequent increased production) but. also in the accurate maintenance of'uniform phys ical properties, since alternate stretching and slacking of the thread during skeining incident to 'arying stress on the thread, may render the thread non-uniform in denier, tensile properties, as well as increasing the danger of breakage.

The vertical adjustability of the bracket 26 permits the angular course of the thread from the guides 38 and 39 to the traverse guides 35 to be varied. Similarly, the vertical adjustability of the platform bracket 19 permits varied spacing of the cakes 22 and 23 from the guides 38 and 39.

The details of construction may be modified in various ways while still obtaining the advantages which flow from the embodiment of the conceptions which underlie what I claim as my invention.

I claim 1. In a skeining machine, a reel. a traverse coo ierating with said reel and having a plurality of guides for forming a plurality of skeins on the reel, a plurality of fixed guides for leading the thread to the traverse guides. means for supporting a plurality of thread masses below the stationary guides. said traverse guides in their median positions and their respectively cooperating lixcd guides and thread masses having their centers substantially in parallel planes normal to the reel axis and median to their respective skeins.

2. In a skeining machine, a reel, a traverse cooperating with said reel and having a plurality of guides for forming a plurality of skeins on the reel, a plurality of tixed guides for leading the thread to the traverse guides. means for supporting a pluralitv of thread masses below the stationary guides, said traverse guides in their median positions and their respectively cooperating iixcal guides and thread masses having their centers substantially in parallel planes normal to the reel axis and median to their respective skeins, and said fixed guides and thread masses being symmetrically arranged on opposite sides of avertical plane parallel to the reel axis and tangent thereto.

2:5. In a skeining machine. a reel. a traverse cooperating with said reel and having a plurality of guides for forming a plurality of skeins on the reel, a plurality of tixcd guides for leading the thread to the ravt-rsc guides. means for supporting a plurality ol thread masses below the stationary guides, said traverse guides in their median positions and their respectively cooperating lixcd guides and. thread masses having their centers substantially in parallel planes normal to the reel axis and median to their respective skeins and said fixed guides and thread masses being synnnetri ally arranged on opposite sides of a vertical plane parallel to the reel axis and tangent thereto. together with means for varying the relative spacing of certain of said parts.

In testimony whereof I have signed my name to this specification.
